Why does 1 em = 1 pica?

Because 1 em = 12pt (default font size) and 1 pica = 12pt exactly. So they're equivalent at the standard 12pt baseline. This clean relationship is why picas are so useful in typography.

I have a CSS design with 1.5 em line-height. What's that in picas for my InDesign layout?

1.5 em = 1.5 picas = 18pt. Use this directly in InDesign's spacing controls for consistent typography between web and print.

If I change my base font size from 12pt to 16pt, does 1 em still equal 1 pica?

No. If 1 em = 16pt but 1 pica = 12pt, then 1 em = 1.33 picas. The conversion only holds at the 12pt standard. Always verify your design system's base font size.

What's the difference between em and pica in print?

Em is relative (depends on font size); pica is absolute (always 12pt). Picas are used for precise measurements; ems for scalable, relative spacing. This converter assumes 12pt em base.

Both ems and picas are typographic units. 1 em equals the default font size (typically 12pt); 1 pica equals 12 points. At the standard 12pt default, 1 em exactly equals 1 pica. This conversion is crucial for print designers using traditional typography tools (InDesign, Quark) who need to convert CSS-based web designs.
